CVE-2025-38471

CVE-2025-38471 concerns the Linux kernel TLS path. The TLS queue can operate on an old skb after aggressive net-next skb compaction, leading to a slab-use-after-free in tls_strp_check_rcv. The Astra Linux bulletin confirms the fix is to always refresh the queue when reading a socket, instead of r...
